MADISON, Wis. & VANCOUVER, British Columbia--(BUSINESS WIRE)--Today, Ostara Nutrient Recovery Technologies (Ostara) and the Madison
Metropolitan Sewerage District (MMSD) officially opened their nutrient
recovery facility at the Nine Springs Wastewater Treatment Plant (WWTP).
The facility will help protect freshwater lakes and rivers by recovering
phosphorus from wastewater streams at the plant, transforming it into an
environmentally responsible fertilizer, Crystal Green®.

The Crystal Green® fertilizer produced at the facility will be available
to homeowners in a new, all-purpose garden blend from Jackson, Wis.
fertilizer blender, Spring Valley.

Unlike conventional phosphorus fertilizers, Crystal Green® is virtually
insoluble in water and instead releases nutrients in response to root
demand, significantly reducing the amount of unused phosphorus that
might otherwise find its way into the watershed.

According to the Association of Wisconsin Lakes, phosphorus runoff
affects an estimated 90% of inland lakes. Excess phosphorus contributes
to the growth of algae, which chokes off sunlight and oxygen, destroying
aquatic life and impairing fish populations.

Spring Valley’s new eco-friendly garden fertilizer blend will be sold at
wholesale and retail outlets throughout Wisconsin.
